PAPER-STRIP-REWINDING MECHANISM.

Application filed. August 7, 1924. Serial No. 730,62.

This invention relates to winding or reeling mechanism and has for its object the provision of a novel device for rewinding the paper strip used on adding machines and the like, whereby the strip may be subsequently reversed, enabling use to be made of both sides.

It is well known that the paper strip used in connection with adding machines is in roll form and is unwound as it passes between the printing rolls of the machine;

Ordinarily there is provided a plate element against one edge of which the paper strip is brought for tearing it off after the des red computation has been made and the pluming completed. Obviously, there is a waste of paper.

It is wit-h the above facts in view that I have designed the present invention which has fora specific object the provision of a supporting frame within which the roll of paper is mounted and within Wl11Cl1 lS a second roll onto which the paper strip 1s wound automatically after passing through the printing mechanism, the frame being capable of opening to permit the insertion of a fresh roll or the removal or transposition of a used roll.

An additional object is the provision of a device of this character which Will be simple and inexpensive in manufacture, easy to 1nstall in association with an already existing adding or other machine, and which will be, moreover, durable and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the combination and arrangement of parts to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the device.

Figure 2 is a plan view.

Figure 3 is a vertical section.

Figure 4 is a vertical section at right angles to Figure 3.

Referring more particularly to the drawings, the letter A designates, diagrammatically, a portion of an adding machine having the co-acting rollers B and G between which the paper strip D passes during the printing operation. The letter represents the metal plate against an edge of which the paper strip may be brought for tearing it off if such is desirable. The ordinary type of paper roll holder is not illustrated as it is replaced by my improved device.

In carrying out the invention I employ an upstanding substantially U shaped frame designated broadly by the numeral 10, which frame includes a base or bight portion 11, a rigid upstanding side member 12 and a movable side member 13 hinged at its lower end, as shown at 14. It is preferable that the hinge mounting includes a spring 15 which will operate normally to hold the movableside 13 in its upright or retaining position. At its opposite sides the base portion of the frame may be provided with extensions 16 through which may be passed any suitable securing means for mounting the frame on the machine A at'the proper location. I i

J ournaled through the sides of the frame are upper and lower shafts or spindles l7 and 18, respectively, which have rectangular intermediate portions 19 and 20 which terminate at one end in reduced cylindrical extensions 21 and 22. The side 13 of the frame is formed with slots 23 which receive the extensions 21 and 22 and the purpose in providing these slots instead of snug-fitting holes is to permit the side 13 to be swung downwardly upon the hinge 14.

The spindles l7 and 18 terminate at their ends in reduced extensions 24: and 25, respectively, permanently journaled through suitable holes in the side 12, and mounted thereon are friction disks 26 and 27, respectively, which engage each other, as shown. The spindles are of course intended to carry rolls 28 and 29 upon which the'paper strip D iswound, the paper being wound initially upon the roll 29 and being adapted to be unwound therefrom and to be wrapped onto the roll 28, the engagement'of the friction disks effecting the simultaneous rotation.

To insure firm engagement of the disks I provide collars 30 and 31 mounted upon the reduced extensions 24 and 25, respectively, and connected by a coil spring 32. Naturally, one hole in the side 12, preferably the upper one, must be somewhat elongated, as indicated at 33, so as to permit the spring to function in drawing the disks togather.

In the operation, let it be assumed that the roll of paper 29 is slipped onto the spindle 1.8. The side member 13 of the frame is then swung or permitted to swing into its upright position, the slots 23 engaging upon the spindle extensions 21 and 22. The end of the paper strip is threaded between the coacting rollers B and C and through the guide plate device E, after which the free end is suitabl engaged upon or with the roller 28. When the adding machine is operated in the usual manner it is evident that the paper strip will be drawn from the roll 29 at each movement of the lever of the machine. The unwinding movement of the roll 29 of course causes rotation of the disk 27 and as this disk engages the smaller disk 26 it is evident that the roller 28 will be turned for winding the paper strip thereonto. After the paper has all been wound onto the roller 28, this roller may be re-' moved from the spindle 17 and engaged upon the spindle 18 so that the other side of the paper may be used. Any necessary slippage occasioned by the difference in the diameters of the two rolls is well taken care of as the friction disks will permit a slippage while insuring tautness of the paper and close winding thereof.

From theforegoing description and a study of the drawingsit will be apparent that I have thus provided a simply constructed, inetqaensive and highly eflicient iviitidin'g or rewinding mechanism which is readily capable of being installed upon already existing machines Without necessitating any material alterations therein. As the parts are few the device is not likely to get out of order and should therefore have a long and satisfactory life.

While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to'make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having now described my invention, 1 claim:

1. In a device of the character described, a frame including a rigid side member and a pivoted side member, means acting to maintain the pivoted side member in normal position with respect to the rigid side memher, a pair of spindles permanently journal- 1y mounted through the rigid side. member,

the movable side member having bearings normally engaging and accommodating the spindles, rolls mounted on the respective spindles, friction disks onthe spindles arranged in contacting relation, and spring means engaging the spindles outwardly of said disks for holding the latter in engagement.

In a device of the character described, an open topped frame including a rigid side member and a movable side member, a spring hinge mounting said movable side member and urging it toward the rigid side member, a pair of spindles journally mounted through the rigid side member, the movable side member having openings normally engaging upon and accommodating the spindles, rolls mounted on the respective spindles, friction disks on the spindles arranged in contacting relation, and spring means engaging the spindles outwardly of said disks for holding the latter in engagement.

3. in a device of the character described, a frame including a bottom member, a rigid side member and a movable side member, a spring hinge mounting for the movable side member urging it toward the rigid side member while permitting outward swinging movement, said rigid side member being formed with a hole and a slot, a spindle journaled through said hole, a .second spindle journaled through said slot, coacting friction disks on said spindles, and spring means urging the second named spindle toward the first named spindlefor maintaining the disks in engagement, said slot permitting relative movement of the spindles.

l. A device of the character described comprising a frame having a rigid side and a hingedly mounted side, a pair of spindles permanently journaled through the rigid side, the movable side having openings normally accommodating the spindles for journally supporting the other endsthereof, a pair of rolls mounted on the respective spindles, and friction disks mounted on the spindles outwardly of said rigid side of the frame and bearing against each other, collars on the spindles rotatable with respect thereto, and a tension spring connecting the collars.

In testimony whereof l affix my signature.
